CC -!- FUNCTION: Catalyzes the initial reaction in O-linked oligosaccharide
CC biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a
CC serine or threonine residue on the protein receptor (PubMed:12829714,
CC PubMed:18669915). It can both act as a peptide transferase that
CC transfers GalNAc onto unmodified peptide substrates, and as a
CC glycopeptide transferase that requires the prior addition of a GalNAc
CC on a peptide before adding additional GalNAc moieties. Prefers EA2 as
CC substrate (PubMed:12829714). In the larval midgut, required for O-
CC glycosylation of apical and luminal proteins within copper cells
CC enabling proper gut acidification (PubMed:22157008).

CC {ECO:0000305|PubMed:12829714, ECO:0000305|PubMed:18669915}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus membrane {ECO:0000250}; Single-
CC pass type II membrane protein {ECO:0000250}.

CC Name=A;
CC IsoId=Q6WV17-1; Sequence=Displayed;
CC Name=B;
CC IsoId=Q6WV17-2; Sequence=VSP_034631;
CC -!- TISSUE SPECIFICITY: Expressed during oogenesis, in the somatically
CC derived follicle cells that surround the developing oocyte, which are
CC involved in the maturation of the oocyte and construction of the egg
CC shell, as well as playing a role in subsequent embryonic pattern
CC formation. During embryonic stages 9-11, expressed in the primordium of
CC the foregut, midgut and hindgut. Expressed in salivary glands from
CC embryonic stage 12 onwards. During embryonic stages 12-13, expressed in
CC the posterior midgut and hindgut. During embryonic stages 14-17,
CC expressed in the hindgut and the posterior spiracles. Expression is
CC also detected in the epidermis and antennomaxillary complex at
CC embryonic stages 16-17. In third instar larvae, ubiquitously expressed
CC in wing, eye-antennal, leg and haltere imaginal disks.
CC {ECO:0000269|PubMed:12829714, ECO:0000269|PubMed:16251381}.
CC -!- DEVELOPMENTAL STAGE: Expressed throughout embryonic, larval, pupal and
CC adult stages, with increasing levels during larval development.
CC Transcripts are first detected during embryonic stages 9-11.
CC {ECO:0000269|PubMed:12829714, ECO:0000269|PubMed:16251381}.
CC -!- DOMAIN: There are two conserved domains in the glycosyltransferase
CC region: the N-terminal domain (domain A, also called GT1 motif), which
CC is probably involved in manganese coordination and substrate binding
CC and the C-terminal domain (domain B, also called Gal/GalNAc-T motif),
CC which is probably involved in catalytic reaction and UDP-Gal binding.
CC {ECO:0000250}.
CC -!- DOMAIN: The ricin B-type lectin domain binds to GalNAc and contributes
CC to the glycopeptide specificity. {ECO:0000250}.
CC -!- DISRUPTION PHENOTYPE: Lethal (PubMed:22157008). RNAi-mediated knockdown
CC in the whole body, embryonic mesoderm, respiratory system or digestive
CC system and reproductive tract is lethal (PubMed:22157008). RNAi-
CC mediated knockdown in the larval digestive system, results in loss of
CC gut acidification and disruption of protein O-glycosylation in copper
CC cells (PubMed:22157008). RNAi-mediated knockdown in hemocytes,
CC amnioserosa, endoderm, mesoderm or nervous system causes no defect
CC (PubMed:22157008). {ECO:0000269|PubMed:22157008}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 2 family. GalNAc-T
CC subfamily. {ECO:0000305}.
